CARCOUPLING.

SPECl'FIC'ATION forming part 0f Letters Patent No. 384,675, dated June 19, 1888.

Application filed September 15, 1887. Serial No. 249,820.` (No model.) l

diana, have invented certain new and useful" Improvements in CarCouplers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to car-couplers, and among the objects of the invention is to provide a coupler that may be operated to couple and uncouple without the necessity of stepping between the cars, that will raise and lower the coupling-link for connection with couplers at different heights, and which,when coupled, will permit of movement of the coupling-link and yet retain the same firmly within the head. l 1

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a substantially central longitudinal section of a car-coupler constructed in accordance with my invention, the parts being in the position assumed when in the act of manipulatingV the coupling-link for connection with a coupler of an approaching car. Fig. 2 is a similar View, the parts being in position to raise the coupling-pin for uncoupling. Fig. 3 is a detail in plan of the carriage, hereinafter more particularly referred to.

Like letters of reference indicate like parts in all the figures of the drawings. A

A represents the draw-head, which is provided with the top and bottom openings, A A2, respectively. Mounted within the draw-head and adapted to slide therein is a carriage, B, through which passes a rod, C,

having its free end provided with longitudinal grooves D and a central groove, D2, and with transverse notches or shoulders D3. Pivoted, as atrE, under the shaft C, within the carriage B, is a lever, E, having its front end bifurcated or notched, as at E2, to embrace the end of the coupling-link` F, and weighted at its opposite or rear end, as atEa, which is` adapted, when the lever is in a position to raise the link for coupling, to dependthrough the opening A2 in the draw-head. Loosely` pivoted in the lever E, in rear of itspivot E', are upwardly-projecting arms E, which are bent in opposite direction attheir upper or free ends, and passing between the grooves D', and adapted to fall into the notches or grooves D3 when said` lever E and the leverD assume y certain relative positions, as hereinafter er;`

plained. A bail, E5, projectsfrom the rear end of the carriage B and embraces and limp At, and a third pulley, A, is j ournaled at the rear end of the longitudinal slot A of the drawhead. A `rope or chain, H, secured at one end to a pin or bolt, D", upon the lever D, passes` through the groove D2 under the pulley A, thence forward through said groove and under the pulleyAB, over the pulley A, and connected with the couplingpin G.

Taking the coupler in the position shown in Fig. 1, to assume this position, which is in the act of raising the link for connection with an ap proachng car, the carriage Bis reciprocated to its rear position within the head. The arms E4 coming in contact with a rod or bar, A1,- extending across the interior of the drawhead, said arms ride up'rmllly upon the same until they pass over` theshou der and into the notches Dformed in the rear end of the lever D. By this means the two leversD and E are made rigid with each other, so that they move together and in unison. The, carriage is now thus raising and lowering its front end, and consequently the link, in conformity with the directionof rotation of the wheel C. By this arrangement the car may be coupled with cars provided with couplers in a different plane with the head A.

To unconple the car and disconnect the link F from the head A, the lever D is swung down to release the arms EL from connection therewith. By simply turning the hand-wheel toward the front the lever Dis raised, which draws upon the rope or chain H and raises the pin A4, when the link may be withdrawn from the head. In a like manner is the pin raised preparatory to receiving'the link for coupling.

The lever D and arms E normally remain disconnected, and can only be connected `by sliding the carriage to the extreme rearend when the arms are connected as before de-A scribed, and in order to maintain this connection the lever D is immediately raised and the carriage slid to the front, in order that the rear end of the link may be embraced and raised and lowered as desired.

Having described my invention and its operation, what I claim is l. In a carcoupler, the combination, with the draw-head thereof, of a movable carriage mounted therein and provided with a linkoperating lever and a pin-operating lever, a shaft for operating the pin-lever, and arms for connecting the pin and link operating levers, substantially as specified.

2. In a car-coupler, the combination, with the draw-head thereof,of alongitndinally-movable carriage carrying pin and link operating levers, a hand-wheel for operating the pinoperating lever, arms pivoted in the link-operating lever and adapted to connect the same with the pin-operating lever, and a rope or chain connecting the pinoperating lever with the pin, substantially as specified.

3. In a ear-coupler, the combination, with the draw-head thereof, of a longitudinally movable carriage mounted therein and provided with a notched and lgrooved' pin-operating lever rigidly mounted on an operatingshaft, a link-operating lever pivoted below the rst-mentioned lever, arms for connecting the two levers, a bail for limiting the movement of said arms, and a transverse bar for raising the arms for connection with the pin-operating lever, substantially as described.

4. In a car-coupler, the combination, with the draw-head thereof, of a longitudinallymovable carriage mounted therein and provided with pin and link operating levers, the latter being bifurcated to receive the link at its front end and weighted and provided with arms at its rear end adapted to take into shoulders formed in the pin-lever and normally held from connection therewith, substantially as specified.

5. The combination of the head A with the carriage B, mounted for movement therein and provided with the shaft G, having the lever D mounted rigidly thereon, and with the lever E, pivoted, as at E', bifnrcated, as at E2, weighted, as at E, and carrying the arms E4, for connection with the lever D, substantially as specified.

6. The draw-head A, having the openings A A2 A3 A4, with the carriage B, mounted for movement within the same and having thc shaft C, carrying the hand-wheel C', and lever D, grooved and notched at its rear end, as at D D`l D3, and with the lever E, weighted,as at E3, and bifurcated,as at E2, the arms E, for connecting the levers, the pulleys A, AS, and A9, the rope or chain H, and the link G, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
